Features:
2*AK4497:AK4497 is flagship model in AKM company. We use a full AK4497 forevery channel in D70s.Resulting in better channel separation and batter spec. THD+N has even exceeded the performance marked by the AK4497 datasheet.

Bluetooth 5.0 L DAC transmission:D70s has the certification of Hi-Res Audio Wireless and LDAC. It uses CSR8675 chipset to support LDACIAAC/SBC/APTX/APTX LL/APTX HD protocol.

Support DSD512 & PCM32bit768kHz High Resolution Music:D70s uses 2nd generation 16 core XMOS XU216, USB supports up to PCM32bit768kHz, DSD512 native and MQA decode. With the help of customized Thesycon driver(for Win 7 or above), your PC will have better performance on ASIO playback.(Mac needn't a driver)

AK4118 receiver:AK4118 is the lowest jtter S/PDIF receiver at present. It has good compatibility which used to receive optical, coaxial, AES signals for D70s,support up to 24bit192kHz.

CPLD:D70s applies the CPLD, focusing on the clock processing and signal optimization. CPLD combines with the accusilicon femto -second to bring a lower jitter effect, while coordinates processing of digital signal optimization to effectively improve signal quality and stability.

Various input interfaces:D70s has various inputs: AES, USB, Bluetooth, Optical, Coaxial, IIS.Both USB and IIS support up to 21bit768kHz & DSD512 native. AES,Optical, Coaxial support up to 24bit192kHz. Bluetooth support 24bit96kHz LDAC transmission.

D70s has full balanced XLR output and single ended RCA output.You can choose "XLR only", “RCA only" or“XLR+RCA”output to meet different usage in the multiple systems.

DAC filter mode:D70s capable of providing 6 filter modes under PCM decoding, 2 filtermodes under DSD decoding, which, slightly adjust the details.(Note: it is not the same as EQ function.)

Bluetooth DAC application:Connect the Bluetooth of your phone, tablet and notebook to D70s so that to become your Bluetooth DAC.
DAC+ Pre amp application,Pure DAC application.
